Pro Co iPlate
Portable Audio Player Interface Wall Plate


The Pro Co iPlate Portable Audio Player Interface is a device that allows simple and reliable connection of the stereo headphone output of audio devices such as MP3 players, Apple® iPods, laptop computers and consumer-type CD and DVD players to the balanced microphone inputs of audio mixing consoles.

The iPlate provides both a Stereo mini 3.5 mm (1/8") and left/right RCA phono inputs for easy connection with standard patch cables and a stereo/mono switch to provide passive input summing to a dual mono output feed where required.

The outputs are isolated via audiophile-grade Pro Co MBT-1 Microphone Bridging Transformers and outputs appear on an easy-to-wire screw-type barrier strip (requiring no crimp terminals) for rapid installation. The transformers offer wide bandwidth and low distortion and phase shift, and are magnetically shielded in mu-metal cans and electrostatically isolated with dual Faraday shields.  The result is near-ideal rejection of common-mode signals from all sources of RFI and EMI, including radio pickup, SCR dimmers and 60 Hz hum.

The GROUND LIFT switch allows correct grounding for either AC or battery-powered sources, eliminating hum and buzz from ground loops between portable and house equipment.

The iPlate is built on a standard-sized dual-gang wall plate constructed of brushed and beveled 1/8" (3.175 mm) anodized aluminum.  All functions are clearly identified by laser engraved legends, providing an attractive and professional appearance in addition to trouble-free technical functionality.
